Advances in Space Research, 2016 Abstract Integer Ambiguity Resolution (IAR) is the key to fast and precise GNSS positioning. The proper diagnostic metric for successful IAR is provided by the ambiguity success rate being the probability of correct integer estimation. In this contribution we analyse the performance of different GPS+Galileo models in terms of number of epochs needed ...

Reliability of partial ambiguity fixing with multiple GNSS constellations
Journal of Geodesy, 2012 Reliable ambiguity resolution (AR) is essential to Real-Time Kinematic (RTK) positioning and its applications, since incorrect ambiguity fixing can lead to largely biased positioning solutions. A partial ambiguity fixing technique is developed to improve

Partial search for multi-carrier GNSS ambiguity resolution
SPIE Proceedings, 2009GNSS carrier phase integer ambiguity resolution is the key for higher precision positioning and navigation. Due to more ambiguities with the multiple frequencies per system, the successful resolution of all ambiguities may not always be possible. However, a subset of the ambiguities can still be possible.

Precision-Driven Partial Ambiguity Resolution Technique for Short to Medium Baseline Positioning
2021 IEEE Aerospace Conference (50100), 2021GNSS carrier phase observations are fundamental for safety-critical applications where the requirements of accuracy and availability are stringent. Upon the deployment of new GNSS constellation and frequencies, the large number of observations can lead to a decreased probability of successfully mapping the real-valued carrier phase ambiguities to ...

Single-Frequency GPS/BDS Combined RTK Positioning with Partial Ambiguity Resolution
2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019Aiming at the problem that the ambiguity of carrier-phase is usually more difficult to fix and the positioning result is less effective when using low-cost receiver for real-time kinematic (RTK) positioning, a combined adaptive partial ambiguity resolution (CA-PAR) algorithm is proposed in this paper. The algorithm adaptively adjusts the boundary value
